PITTSBURGH, Sept. 16 - John Waryold, an well-known expert in conformal coating and a 44-year veteran of electronics manufacturing, retired from HumiSeal effective Aug. 31. He will continue to advise the company in a lesser role.

Waryold, who for the past 20 years was vice president and general manager at HumiSeal, was also chairman of the task group responsible for most of the conformal coating standards in use today. 

Waryold spent 44 years at HumiSeal, beginning his career in 1960 as a lab researcher and also holding positions in technical service and sales. He invented 1B31 and several other products that have become industry standards.

He authored several papers, and a chapter on conformal coating in the Printed Circuit Handbook. Waryold received the IPC President's Award in 2000 for chairing the task group that wrote IPC-CC-830.
